This, unfortunately, is WAY too abstract. You had me on those 10 first seconds, the minimalistic intro, the ambient sounds... but then, disappointment. It's trying too hard to be mysterious. Transitions didn't help at all, that amount of gaussian blur was distracting. Also, I couldn't find a meaning behind this little story (actually, there's no story at all, just a train passing by), is it about the loneliness of a youngster? Is it about solitude generally? It was a very long shot, and unfortunately for me, it failed.

I would recommend you to watch Brain Kepher, it's the best example of what you might do with similar ideas.
